Boston ? The Boston Red Sox tried to bolster their bullpen with yet another left-hander, getting Mike Remlinger and cash from the Chicago Cubs on Tuesday for minor-league pitcher Olivo Astacio.

Remlinger made his Red Sox debut Tuesday against Texas but failed to record an out, starting the seventh inning and facing four batters before leaving with the bases loaded.

Right-hander Wade Miller was placed on the 15-day disabled list with right shoulder stiffness to make room on the roster for Remlinger. Miller, 4-4 with a 4.95 earned-run averaged, also missed the first 30 games of the season while recovering from a strained right shoulder.

Also Tuesday, the Red Sox traded outfielder Jose Cruz Jr. to the Los Angeles Dodgers for a player to be named. Cruz was acquired from Arizona on July 30 and went 3-for-12 in four games for Boston before he was designated for assignment Monday.

The AL East-leading Red Sox cut lefties Alan Embree and John Halama last month, and Remlinger was designated for assignment by the Cubs on Friday.

The 39-year-old Remlinger was 0-3 with a 4.91 ERA in 35 games with Chicago.

Remlinger had been one of the most reliable and durable lefty setup men in recent years. He was an NL All-Star in 2002 with Atlanta, which came during a stretch in which he made at least 70 appearances in five straight seasons.
